An example FFT algorithm structure, using a decomposition into half-size FFTs A discrete Fourier analysis of a sum of cosine waves at 10, 20, 30, 40, and 50 Hz A fast Fourier transform ( FFT ) is an algorithm that computes the Discrete Fourier Transform (DFT) of a sequence, or its inverse (IDFT).
Smaart is a real-time single and dual-channel fast Fourier transform (FFT) analyzer. Smaart has two modes: Real-Time Mode and impulse response mode. Real-Time mode views include single channel Spectrum and dual channel Transfer Function measurements to display RTA, Spectrograph, and Transfer Function (Live IR, Phase, Coherence, Magnitude ...
Musical sound can be more complicated than human vocal sound, occupying a wider band of frequency. Music signals are time-varying signals; while the classic Fourier transform is not sufficient to analyze them, time–frequency analysis is an efficient tool for such use. Time–frequency analysis is extended from the classic Fourier approach.
This is a list of linear transformations of functions related to Fourier analysis. Such transformations map a function to a set of coefficients of basis functions, where the basis functions are sinusoidal and are therefore strongly localized in the frequency spectrum. (These transforms are generally designed to be invertible.)
FreqTweak is FFT-based, and supports up to four channels. An FFT analysis is applied to each audio channel, and every individual frequency band can have a different effect applied to it. In version 0.6.1 the following effects are available:
This category is for fast Fourier transform (FFT) algorithms, i.e. algorithms to compute the discrete Fourier transform (DFT) in O(N log N) time (or better, for approximate algorithms), where is the number of discrete points.

An FFT analyzer computes a time-sequence of periodograms. FFT refers to a particular mathematical algorithm used in the process. This is commonly used in conjunction with a receiver and analog-to-digital converter. As above, the receiver reduces the center-frequency of a portion of the input signal spectrum, but the portion is not swept.
